IMPROVEMENT m VENTILATING AND WARMING pRoMs.

Specification forming part of Letters Patent No. 169,074, dated January 26, 1875; applicationfiled December 12, 1874.

To all whom it may concern:

Be it known that I, PETER H. OARMAN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Ventilator and Warmer, of which the following is a specification:

The invention will first be fully described, and then pointed out in the claims.

- 1n the accompanying drawing, Figure 1 represents a sectional side elevation of the ventilator and warmer. Fig. 2 is a vertical cross section of Fig. 1, taken on the line a: m. Fig.

' 3 is a top view. Fig. 4 is a horizontal section of Fig. 1, taken on the line y 3 showing the tubes and the position of the partitions, the upright foul-air flue being left ofi'.

Similar'let-ters of reference indicate corresponding parts. I

This ventilator is placed in a fire-place, or

' in a room or apartment of a building, or in any position'w'here it can be connected with a flue or chimney of a furnace or fire. It may be made 'square or angular, as seen in the drawing, or circular, as may be desired. 4

In this example of my invention the ventilator is rectangular in cross-section, and of a height about equal to the breadth, thus forming a box, A, in which are horizontal partitions B, G, and D, and vertical partitions E and F. G are tubes of greater diameter at the bottom than at the top, which extend from the lower partition, B, to the upper partition,

0, all passing through the central partition, D, with the exception of the outside tier. This central partition is cut short at the point H to allow the heat to pass from the lower compartment, I, to the upper compartment, J,

by means of the lines K L. M represents the chimney or fire-flue, and N is a damper between the flues K L. Above and below the horizontal partitions B G are two compartments that is, two above and two -belowmarked 0 P and Q R. There are six tiers of tubes shown, half of which connect the compartments O and Q, and half connect the compart-ments P and R. On the top of the Vantilator is a discharge-aperture for each of the Y compartments 0 P, marked S and T.

The fresh air is admitted into thecompartment Q, by means of an air-tube, and passes up through the left-hand tiers of tubes G, by

means of which the' air is heated and discharged into the chamber 0, from whence it is conveyed through the aperture S to the apartment, or to any desired place. At the.

same time the foul air at the bottom of the apartment is drawn into the chamber R, an upward draft being induced by theheat with which the .tubes are surrounded, and is carried into the chamber P and discharged into a chimney-or fluc,.nnd. -conductedfrom the... building.

U represents a flue forcarrynig olf foul air, through which an upward draft is produced by means of heat, or by its extended length,

and a down-draft is induced through the ven-. 'tilator tubes G. Apertures may be made in :this flue for drawing the air from the upper apartments of a building while such air is sup- 1. The combination of connected chambers,

Q 0 P R with tubes G, as and for the'purpose described.

'2. The combination, with tubes 6., of the.

chambers I J ,connected by tubes L K with the dampere'd pipe M N, as and. for the purpose specified.
